MECHANISM FOR DRIVING TRAVELING FLATS.

SPECIFICATION forming part of Letters Patent'No. 570,829, dated November3, 1896.

Application filed April 30, 1896. Serial No. 589,736. (1T0 model.)

To all whom, it may concern.-

Be it known that we, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPHSMALLEY, subjects of Her Majesty the Queen of Great Britain, residing atCastleton, Manchester, in the county of Lancaster, England, haveinvented a certain new and useful Improvement in carding-Engines, ofwhich the following is a specification.

This invention relates to an improvement in the mechanism employed fordriving the flats of flat-carding engines and appliances connected withsuch mechanism.

The object of the invention is to insure efficient lubrication of theworms and wormwheels of the flat-driving shaft, to protect the same fromdust and dirt, and to allow of the parts being readily disconnected, sothat the chain of flats can be turned by hand.

Referring to the accompanying drawings, Figure 1 is a side elevation ofpart of a flatcarding engine, showing the position thereon occupied bythe said improvements. Fig. 2 is an end elevation of part of aflat-carding engine with the improvements applied thereto. Fig. 3 is aside elevation of Fig. 2. Fig. 4 is a similar view to Fig. 3, butshowing the comb as operated by mechanism preferably adapted when thecleaning-brush is driven slowly, as is sometimes the case.

In carrying out our invention we inclose in a casing 1 a shaft 7,carrying a worm 2 and at its end a worm-wheel 4. At the end of thecasing 1 and superposed on same is a further casing 1, which incloses aworm 3, carried by a stud 3, which also carries the drivingpulley 25.

Hinged at the point 13 to the casing 1 is a further casing 13, whichincloses a wormwheel 5, which engages with the worm 2 and is carried bya shaft 6, which drives the starwheel (5, over which the chain of flatspass. The casings prevent loose fibers and dirt accumulating on theparts they inclose.

The bottom of the casing 1 serves as a receptacle for oil and insuresthe parts being efficiently lubricated. On the shaft 7 for supportingthe lower worm 2 and wheel 4 we form a key or float S, a keyway 9 beingformed in the worm 2 and wheel 4 for its reception. This shaft isarranged to slide in theworm 2 and Wheel 4 and is provided with twoannular grooves l0 11, cut in its circumference. A stop-piece or stud12, passing through the casing, is provided to fit these grooves. Whenthe stop-piece is in one groove, 10, the worm. 2 and wheel 4 areconnected by the key or float 8, but when shaft 7 is drawn outward andthe stop-piece 12 is put into the other groove, 11, the wheel 4 isdisconnected from the lower worm 2, and the shaft 6 and flats can bedriven by the shaft 7, if a suitable handle is provided for it, throughthe medium of the worm 2 and worm-wheel 5.

When driving by power from the pulley 25, the transmission takes placethrough worm 3, worm-wheel 4, worm 2, and worm-wheel 5. The stud 3 alsocarries a pulley 15, which drives, through the rope 15, a pulley 15 011the shaft 15 of the brush-roller 26.

Upon the shaft 15 we place eccentrics 14, one at each end of the shaft.Each of these eccentrics carries one end of a connectingrod 16, theother end of the rod being connected at 17 to the curved lever 18,secured by nuts 19 to a bracket 19 on the rocking shaft 19, that usuallygives motion to the comb 20. By fixing the comb 20 a short distance fromthe lower ends of the eccentricrods 16 thecomb-blade partakes of aportion of the motion of both the eccentrics and the levers from therocking shaft, and thus causes the comb to pass nearer the flats on itsdownward stroke than it does on its upward stroke, and so enables thecomb to be set closer to the card-teeth without liability of. damagebeing done to thewire on the flats.

When the brush-roller shaft 15 is to be driven slowly, as is sometimesthe case, the pulley 15 is mounted on an extension 27 of a bracket 28,Fig. 4, and drives through its shaft 29 a pinion 30, which in turndrives a spur-wheel 31 on the shaft 15, an open driving-rope 15 beingemployed between the pulleys 15 and 15. In this case the eccentries 14for working the comb 20 are fixed on the quick-running shaft 29, whichcarries the pinion for driving the brush-shaft 15, so that the requisitequick motion for the comb is obtained. The eccentrics 14 being driven ina reverse direction, it is necessary that the centers 17, or pointswhere the connectingwheel shaft 6, as shown, instead of being connectedwith the rocking shaft, as shown in Fig. 3.

To adjust the throw of the comb 20, ascrew 17 and nut 18 are employed,the arrangement enabling the point 15 to be moved along the slot 17 ofthe levers 18.

To prevent dust or dirt collecting or re maining on the periphery of thecircular plates or disks 22, which carry the flats when being cleaned bythe stripper-comb, we employ a weighted lever 21, loosely hung on theshaft 19, the tooth 21 of which rests on the periphery of the disk orplate 22 and acts as a scraper on same.

W'hat we claim is 1. In a carding-machine, and in combination, the chainof flats, and a star-wheel for driving the same, a worm-wheel operatingsaid star-wheel, .a worm driving said wormwheel, a shaft carrying theworm, a long key on said shaft, a second worm-wheel also carried by saidshaft, grooves for the key in both the worm and worm-wheel, whereby theshaft may rotate with both worm and worm-wheel or when drawn outlongitudinally may be used to rotate by hand the worm only, means forholding the shaft in either position, a second worm which engages withthe second worm-wheel and means for driving the latter wormsubstantially as described.

2. In a carding-engine, and in combination, the chain of flats, and astar-wheel for driving the same, a worm-wheel operating said star-wheel,a worm driving said wormwheel, a shaft carrying the worm, a long key onsaid shaft, a second worm-wheel also carried by said shaft, grooves forthe key on both the worm and worm-wheel, whereby the shaft may rotatewith both worm and worm-wheel or when drawn out longitudinally may beused to rotate by hand the worm only, means for holding the shaft ineither position, a second worm with which engages the second worm wheel,means for driving the latter worm and a casing covering both of theworms and their worm-wheels and adapted to contain lubricating materialsubstantially as de scribed.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
